President Donald Trump on Wednesday said Attorney General Jeff Sessions “should stop this Rigged Witch Hunt” in a series of tweets critical of special counsel Robert Mueller.

Trump’s tweets said the special counsel’s charges in the current trial of his former campaign chairman, Paul Manafort, “have nothing to do with Collusion—a Hoax!” The Washington Post, the New York Times, NBC and Politico have stories.

Trump’s tweet about Sessions was posted nine minutes after one that ended with “ALAN DERSHOWITZ …” It read: “This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further. Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA!”

Mueller is reportedly examining past Trump tweets and remarks about Sessions as part of a probe into obstruction of justice, the New York Times had previously reported.

Trump’s tweets about the Russia investigation on Wednesday began with condemnation of FBI agent Peter Strzok, who had criticized Trump in texts to an FBI lawyer. Strzok had worked on both the probe of Russian influence in the 2016 election and the investigation of Hillary Clinton’s use of a private server for email while secretary of state.

Trump said Strzok was out to stop Trump from being elected and he should not have been allowed to remain in the FBI. “Those are illegal, improper goals, trying to influence the election,” Trump tweeted, adding in a later tweet that “this is a real issue,” but “it won’t go into a Mueller report because Mueller is going to protect these guys.”

In the past, Trump had said 13 Democrats work for Mueller, but “upped the figure to 17” in his latest tweets, according to Politico.

Russian Collusion with the Trump Campaign, one of the most successful in history, is a TOTAL HOAX. The Democrats paid for the phony and discredited Dossier which was, along with Comey, McCabe, Strzok and his lover, the lovely Lisa Page, used to begin the Witch Hunt. Disgraceful!

Paul Manafort worked for Ronald Reagan, Bob Dole and many other highly prominent and respected political leaders. He worked for me for a very short time. Why didn’t government tell me that he was under investigation. These old charges have nothing to do with Collusion - a Hoax!

..This is a terrible situation and Attorney General Jeff Sessions should stop this Rigged Witch Hunt right now, before it continues to stain our country any further. Bob Mueller is totally conflicted, and his 17 Angry Democrats that are doing his dirty work are a disgrace to USA!

…..remain in the FBI while he himself was being investigated. This is a real issue. It won’t go into a Mueller Report because Mueller is going to protect these guys. Mueller has an interest in creating the illusion of objectivity around his investigation.” ALAN DERSHOWITZ….

“FBI Agent Peter Strzok (on the Mueller team) should have recused himself on day one. He was out to STOP THE ELECTION OF DONALD TRUMP. He needed an insurance policy. Those are illegal, improper goals, trying to influence the Election. He should never, ever been allowed to……..
